Treatment often involves potent drugs with unwanted side effects. The technological–pharmacological combination of capsule endoscopy with ultrasound-mediated targeted drug delivery (UmTDD) described in this paper carries new potential for treatment of these diseases throughout the GI tract. We describe a proof-of-concept UmTDD capsule and present preliminary results to demonstrate its promise as an autonomous tool to treat GI diseases.","PeriodicalId":447761,"journal":{"name":"J.

The mechatronic design, which is transferable to other robots, adapts to the existing communication infrastructure of the robot and therefore offers real-time capability. Besides the interaction with the robot itself, it also allows the control of third party devices connected to its communication network.

Micro-surgeons are targeting sub-millimeter-sized structures here. Tiny vessels or wafer-thin membranes are to be cannulated or need to be peeled off. The greatest care is to be displayed not to damage these fragile structures or to inadvertently injure the underlying retina. Damage to the latter is mostly irreparable and might cause permanent loss of vision. Despite the availability over excellent stereo microscopes, wide-angle lenses and powerful light source visualization remains a problem. Especially, the limited depth perception is still perceived as a major bottle-neck whereas efforts have been conducted to integrate sensing capability in today’s state-of-the-art instruments, so far, little effort has been paid to process the obtained sensor data and turns this into a reliable source of information upon which robot assistive guidance schemes could be endowed upon.

Although PIVC is often easy and successful in adults, it is a very difficult procedure for young pediatric patients. Multiple attempts of catheter insertion are typically needed before a successful placement, especially for clinical personnel lacking specific expertise on this task. The risks of such multiple attempts can be severe and life-threatening as they can cause serious extravasation injuries. Given the levels of precision and controllability needed for PIVC, robotic systems have large potential to effectively assist the operation and improve its success rate. Therefore, this research aims to provide such robotic assistance by focusing on the most challenging part of the operation: the insertion depth control to precisely access the target vein. A handheld robot for controlling the insertion and detecting venipuncture is introduced and evaluate...","PeriodicalId":447761,"journal":{"name":"J.

However, such systems have two distinct shortcomings: they require continuous information about the location of the instrument inside the human body and they rely on models that accurately capture the device behavior, which are difficult to obtain in realistic settings. To address both of these issues, we propose a control algorithm that continuously estimates a magnetic endoscope’s response to changes in the actuating magnetic field. Experiments in a structured visual environment show that the control method is able to follow image-based trajectories under different initial conditions with an average control error that measures 1.8 % of the trajectory length. The usefulness for medical procedures is demonstrated with a bronchoscopic inspection task.

The performance of the proof-of-concept device is analysed through controllability and the usability studies. The computer-controlled high-speed scanning demonstrates repeatable results with 21 um precision and a stable response up to 48 Hz. Teleoperation user trials, were performed for trajectory-following tasks with 12 subjects, show an accuracy of 39 um.
